Question

Total XAML noob here. I’m having problems determining the proper way to change the background color on a Button element for the pressed state. It seems the default button background is white. How do I make it some other color (with transparency). Code snippet would be very helpful.

Answer 1

The default template for Button uses a resource for the Pressed state’s Background named “ButtonPressedBackgroundThemeBrush”. If you want this to change for all Buttons in your application you can override this in your App.xaml resources by adding a Brush using the same key. Here’s an example using solid red:

<Application.Resources>
    <ResourceDictionary>
    <SolidColorBrush x:Key="ButtonPressedBackgroundThemeBrush" Color="Red"/>
    </ResourceDictionary>
</Application.Resources>

If you only want a single Button to use a different Background you can override the Template. The easiest way is to use Blend and right-click the Button, and select Edit Template->Edit a Copy. This will generate a copy of the XAML for you and you can either use the States tab or edit the XAML for the Pressed state by hand.
